PanelDue

PanelDue cable does not run near motors. But I will do it differently.

could you answer my question about the movement along the axes with mesh compensation enabled? Should the bed move?

I just can't figure it out.

Yes, but it's hard to see whether the Z motors are moving a little or not on most printers. For example, with 400 Z steps/mm @ x16 microstepping on 1.8deg motors, the leadscrews will turn only 1/10 turn for 0.4mm movement.

[Dep]

@dc42 In fact of the matter. I attached a long stick to the pulley. There is no movement and no sound.

And during printing, the compensation does not work.

[dc42]

Run M122 and check that it reports "Bed compensation in use: mesh" while it is printing.

[Dep]

@dc42
I usually do that.

The size of the table at the printer is 1x1 meter. And the unevenness is about 0.5mm. I usually see the Z motors move.

Should I try to install an older firmware? Or does everything work for you?

[Dep]

Another dangerous bug!

M558 K0 H5 A5 F120
Works as it should

M558 K0 H5 A5 F120: 120
Also works as it should

M558 K0 H5 A5 F120: 60
Broke today probe.
The bed goes up and breaks the probe. And continue to rise.

I checked it several times.

Broke today probe.

Why would you use F120: 60 at all?

To better understand why the mesh isn't moving the Z axis please provide your config.g and homing files so we can see what other commands are taking affect.

What's in that macro?

@Dep said in Strange bugs 3.3beta2:

M98 P"homex.g" M98 P"homey.g"

Can you share these as well?

Can you also share the results of sending M98 P"config.g" and share your slicer start gcode.

M376 H20 ; bed compensation taper

With a taper set the amount moved to compensate is diminished over the duration of the print and for small amounts can make it very hard to see.

Can you post a screenshot showing your heightmap?

How often do you re-create the heightmap?

[Dep]

I've done it many times. The print shows that the compensation does not work. I also attach a long stick to the pulley to check if there is movement or not.

If necessary, I can shoot a video.

I've tried disabling taper. M376 H0
Nothing changes.

add G29 S1 after the G28 in your start script

[Dep]

@jay_s_uk It is added:

homeall.g (G29 S1 here)

; homeall.g
; called to home all axes
;
M98 P"homex.g"
M98 P"homey.g"
M98 P"bed.g"
G29 S1

[jay_s_uk]

@Dep ah, missed that

[Phaedrux]

All I can think is that the conditional gcode in your homing files is skipping something.

Can you try adding G29 S1 to your slicer start gcode after the purge filament macro?

Then check if mesh compensation is active in M122 during the print and see if the Z axis is moving.

[OwenD]

Could it be that you're not homing Z after you run bed.g ?
